Invalid Key for Install

Referring to this tutorial: http://www.asp.net/webmatrix/tutorials/download-and-install-an-asp-net-application

I selected umbraco cms and got this wizard:

I already have Standard Sql Server 2005 on my machine which I wanted to us for above DB and not SqlExpress.

I did not remember "sa" account pwd nor I use explicitly any account to connect to my Sqlserver. I use Windows Authentication account i.e implicit authentication. So I created new account and gave all rights and used it in the above wizard and was able to install the database after some struggle.

My question is: What if I want to use my Windows Account to install the database above? Why the wizard don't have any option to use Windows Integrated Authentication?

Note: I can create the DB with external user I created, just looking specifics for using Windows Authentication for above installation.

To my displeasure I cannot find VWD2005 which at one time would generate a complete web.config for Ajax so I downloaded and installed VWDE 2010 to a clean install of XP Pro.

I've created a new tab on the toolbar for the controls but after I select the Ajax dll to add the controls to the toolbar it grinds away and then goes poof and closes down the task leaving VWD look as if I had never even created the tab in the toolbar. 

Any advice here?

which edition of sql server  are best for me  Developer edition or express editon for development purpose.

i try to install last time sql server in my system but not successful so what i do for get the sql server in my system.

Hi guys really new to ASP.NET I was trying to install the CSS Friendly control adapter but for some reason the instructions on the website seems outdated. I downloaded all the files (Source Code, DLL, Browser) I believe I need to add the DLL file to my website's Bin folder and the Browser file to the APP_Browsers folder is this correct? After I place this files how to I get it working? what do I have to do?

Also if I want to create a new DLL file from the Source code how do I do these? I opened the web-site with Visual Studio 2008 and I can see all the files in the solution explorer? But how do I compile this to a DLL file? I tried doing a build solution but all I get is an .sln file???

Any help would be greatly appreciated

Thanks in advance

I've read up on this error from other posts and on other sites, but haven't found a solid resolution to the issue yet. My setup is as follows:

I have a RepositoryBase class that fields certain db calls that all repositories need to perform. In one such call, "GetSecurityGroup", it works most of the time, but will seemingly at random throw an exception with the error "Invalid attempt to call Read when reader is closed." All other Repository classes inherit from this one, and they all use the same DataContext object, which I understand isn't thread safe. Since there could be multiple calls to the DataContext object on the same page, perhaps one is using the DataContext when the next tries to do so. I'm not sure. What can I do to ensure this doesn't happen?

Hi,

How can I catch this exception? I do not want it to stop my page execution. Can/Should I do that?

Server Error in '/' Application.
